The present invention provides a method of reconstructing a tomographic image. In a first step, a tomographic image is forward-projected along a list of geometrical lines in a GPU. This list of geometrical lines may be list-mode event data acquired from a tomographic scanner. Alternatively, the list may be a list of weighted lines derived from a sinogram, a histogram, or a timogram acquired from a tomographic scanner. Next, the list of geometrical lines is back-projected into a 3-dimensional volume using the GPU. The results of the forward- and back-projection are then used to reconstruct the tomographic image, which is then provided as an output, e.g. to make the image available for further processing. Examples of output include storage on a storage medium and display on a display device.

In positron emission tomography, a nuclear medicine scanner is utilized to detect γ-ray events resulting from positron annihilation events. Molecules with known behaviors are tagged with radioactive isotopes which decay into γ-ray pairs which are detected coincidentally, i.e. in a near-simultaneous fashion, by radiation detectors. A temporal recorder and a subject support monitor indicate the time and position of the subject when the coincident γ-rays were detected. A storage buffer collects γ-ray detection times and locations along with support positions. Every 1 / 100th- 1 / 10th second, a batch of data collected in the buffer is reconstructed into overlapping portions of an image memory as the support moves continuously through the scanner.
